Immortals debuted to an estimated $32 million, which is less than half of 300's $70.9 million and also way off from Clash of the Titans's $61.2 million. While those are both very similar movies, it's a slightly unfair comparison given the marketing dominance exercised by their distributor Warner Bros. In its own right, Immortals was actually very impressive. It is distributor Relativity Media's best opening ever by a long shot (Limitless was the previous high with $18.9 million), and it's also the top opening for a movie not released by a big six studio since Lionsgate's The Expendables debuted to $34.8 million last August. Finally, it's the second-highest opening for an R-rated 3D movie ever behind Jackass 3-D's $50.4 million, with 3D showings accounting for a substantial 66 percent of the weekend gross. The movie's audience was 60 percent male, 75 percent under the age of 35, and 35 percent Hispanic. Immortals received a "B" CinemaScore, and a "B+" from the under-25 crowd.

"Immortals": Simply put, I've never seen anything like
the violence in "Immortals." It's easy to say that the slow-motion
style is just a "300" ripoff, but it's not. In that film, characters
moving slowly was a stylistic choice. In "Immortals," the
time-disorienting motion is inherent to the nature of Gods and Titans,
resulting in one of the single most breathtaking battle scenes I've ever
seen committed to film, ever. Again, I have never seen
anything like those final 20 minutes of "Immortals." It's some of the
most beautiful violence I've ever witnessed on the big screen. ('Immortals' Versus '300': Pound For Pound via mtv.com
